and use. Also theprinting press must reduced in speed until at themoment of I-"z plenishment-it is' -barely in motion and thev aixing ofthe forward end of thel new web l to the rear end of'the expiring webhas had to be done mainly by hand. The web of the old roll has beensevered on its core by hand while'I the motion of the other parts of'the' device had to vbe guided manually; VThese defects rendered themachines subject to uncertain operation on account, of the manualcontrol of 'certain features and didnot materially increase the speedofprinting because of the need of practically stopping the printing rmachines. The-main object of theseinventions has been to reduce thestoppage 4of the printingmachin'e as much aspossible. d above, thepresent invention is y As statef designed or the purpose ofv effectingthe.

change automatically andwithout need of hand manipulation and withoutanynreduc-r tion in the' speed or yproduction of the press -it requiresis tobe set `by very simple ac- .tion atany time before operation andthen to start the. machine.l Then it will operate at a timedetermined-by the position of the parts ply for the old one while thepress is running at full speed so that there is no reducing of the rateof production.

' Referring to the drawings, the paper replen-Al ishin printing press,only a part of the frame 10 device is shown as located beneath a ofwhich is shown in the drawings. The replenishing device is shown assupported on two pillars 11 resting on afoundation. Be-

tween these pillars is a shaft 12 on one end of which is located a wormgearl 13 which meshes with a worm pinion 14- on the shaft of a vmotor15. By means of this method ofdrive, the shaft 12 can be rotated andheld 15 firmly in any position in which ,it may be when the motor isstopped. vlhis motor is intended to be operated intermittently as may bedesired for the purpose of turning the shaft 12 one third of arevolution at a time.

2 'The' shaft can be turned by harld if desired.

Fixed on the shaft 12 between the pillars and adjacent to eachl of themare two-spiders.

Each of these. spiders is made up of a hub 16 I j and three arms 17 Intheend of each of the spider arms is held amandrel 20 by means of ascrew 18 entering a slot 19 in the mandrel. The mandrels on one set ofspider arms are n opposite the mandrels on the corresponding spiderarms. These mandrels are for secur-v 0 ing in the space between themthel paper rolls which are wound as usual upon cores 21 in the formofpieces of pipe. The inner ends of the mandrels 20 are conical so thatthey may slipinto the opposite ends of the cores 21. Upon theI extremeconical end of each mandrel is a fixed key 22 which fits into a key-waycut into the end of the core, as shown in Fig. 4. It v, will be obviousthat when a roll of paper is placed between a pair of spider arms andthe respective mandrels are inserted into its core,

Vthe roller will be left suspended upon these The rot-ation of ,thejwhole frame mandrels'. consisting of thelsix arms 17 bythe motor 15 isthe meansused for raising and lowering the heavy rolls of paper. e

As there are three -pairs of spider arms all similarly equipped, threerolls of paper may Vbe carried at onetime by this device. In Fig. 5 Ihave designated the charging. posi- .tion C,preplenishing position B-andthe running position`A .of the rolls. This may be considered theposition of the paper rll carrying magazine at the beginning of the op:I

eration ofthe press. Fig. 1 shows the situation after the roll'A whichis supplying theweb'W has been re- 'l duced down to a position in whichit is. time to .connect the web with the second roll and con- .tinu`e.thesup'ply to the pressfrom that roll.

Thevweb runs from the expiring roll A on the arms 17 upwardly to aspring tension roller 25 which is? carried between levers 26 pivoted onthe base or framell() of the press.

Lees-,eee

a stationary roll 28 to the printing press above. rllhis descriptionapplies to both po- A sitions shown in Figs. 1 and 5 and, in fact, toall positions'as Athe roll that is delivering to the press is alwayslocated in the position A after it is once connected with the runningweb. I

Two leather belts 30, engaging the roll A near its ends, run in thedirection in whichthe web runs to the press at web' speed for thepurpose of assisting the rotation of the roll A which is Lfeeding theweb. Each endlessbelt 30 is suspended between two drums 31 and 32, theupper one of which is mounted onea shaft 33. This shaft is positivelydriven through'axsproclfet 34 mounted on the shaft, I driven in turn bya chain from a sprocket 36 operated by the press, the operation of whichis not illustrated herein. In this manner, it willbe seen that wheneverthe press runs the belts also will run and the paper roll against whichthey contact will rotate at whatever speed the press is moving. So theroll is mounted are located at a point almost directly under the centerof the shaft 33 it Will be seen that, whether the paper roll A is largeor small, the belts will lie snugly its surface in such manner that theycan rotate itby .theirf propelling action upon it.

There are three arms 38 articulated loosely abo-ut the shaft 33 abovethe replenishing roll B. One is located at each side of the replenishingroll and one between them so that they all extend over the surface ofthis roll. Throughthe outer ends of these arms runs a shaft on whichthere are fixed three rubber l faced `propelling rolls 39.

This shaft is driven through a chain 29 from a sprocket wheel on theshaft 33` and this sprocket is driven' from the press as has beenstated. It

will be seen,.therefore, that when the propelling rolls 39 are incontact with 'the upper paper rolLB they will propel it at the surfacespeed of the press in the same direction in which the paper is beingdrawn from the rollinFig. 1. f, U y y It -is to be observed that on thepillarsll a pair of arms 41 are pivoted and provided with a convexshield 42. `The arms 41 are articulated to a pair of links 40 extendingup- 'Wardlywhich are lconnected to a rock shaft 43 through arms 44xedthereon. At the end of the rock shaft 43 there is fastened an armL 130Springs 27 support the armsand the roller 25. The web then passes to theleft and up around lvil) 45 which carries a stud 46 upon which isarticulated a spring rod 47 carrying a strong spring 48. This rod slidesin a bearing 49 on a bracket conveniently fixed on the press,y

trigger notch 51. In this notch lies a trigger 52 constituting the endofan arm 53 pivoted on a bracket 54 fixed on the bottom of the press',if desired. The pressureof the spring 48 is exerted to turn the shaft 43backwardly to the dotted line position shown in 3 but normally this ispositively prevente Vby the trigger 52.

Swiveled on the rock shaft 43 is a hand lever 59 carrying a bolt 60adapted to enter a drilled hole 61 in acolltar 58 fixed on the rockshaft.v .This bolt 60 is pressed by a spring 62 into locking positionandis' provided with a hand grip 63 for withdrawing it. It is by meansof this that the rock shaft is turned to the full line position shown inFigs. 1 and .3 and cocked in that position against the action of .thespring 48. From consideration of the parts so far described it will beobvious that the turning of the hand lever 59 from its horizontalposition around to la `lower posivtion in line with the laxis of thenotch 61 has turned therock shaft to the position vshown in Figs. 1 and3. The handle is shown there as spring 48 the -with the shiel the upperweb roll.

in the position to which it is brought after A the hand' grip is movedto'disengage the bolt from the notch 61 but under the action of the(parts are left in this position holding the web away from It has.beencustomary in machinesjfor this purpose to cover the forwardor'leadingedge of the paper on the replenishing roll,.-in this caseindicated at B, with paste as indicatedat 64 in Fig. 7, except that inthat ligure I have shown. the roll as having three areas 65 Ientirelyfree from `paste. The rolls 39 are spaced as shown in Fig. 7 in the samerelation as the clear spaces 65. This is to-provide la free unpastedpath for these rolls to travel over so that no rpaste will borne intocontact with them. The points of-the leading edge of the web onythis'roll are held to the roll by means of grease.

If it were not for the shield 42 the web would come into contactl withthis web roll oneach mandrel 20, at one end of the machine. On accountof the fact that this mandrel is" secured tothe paper roll through itskey 22 it isv clearthat the mandrel will turn s positively with thepaper roll if that is rotated andthus the cam.66 will rotate in exacttime wlth the paper roll. It is to be observed that the cam 66, as shownin Fig. 5, corresponds in radial position with the center of theposition at which the pasted portions 64 are located on thecircumference of the roll. The lever 53 on which .the trigger 52 ismounted is connected through a stud 67 with a vertical rod68 whichpasses downwardly through an eye 6 9 carried by a horizontal push rod 70. This push rod 70 is carried by an extension 71 on one of the pillars11 and a bracket 72 carried by a rod 3 which protrudes inwardly from theextension 71 of the pillar at'that end. On the inner end of the rod 73is articulated loosely a finger 74. The vertical plane of this finger 74is the plane in which is located the cam 66.A Therefore, as the rollrevolves, the cam will raise the finger 74 once during each rotation.The rod 68 which hangs from the ,lever 53 is normally located at oneside of the vertical planel in which the finger 74 moves upfand down sothatit will not be moved by it. Butti-'lis rod 68 is free to swingsidewise' slightly and can be so moved by the rod 70. This is movedtothe left by pressing on a knob on its end against the action of thespring 75 which normally keeps it in inoperative position. It is plainthat when this rod is pushed inwardly it will carr the end of the rod 68intoA the path of the nger 74 and the next time said finger rises itwill lift the trigger arm 53 and thus disengage `the trigger 52 from thenotch 51. Now, the spring 48is free to operate and'it moves the arm 45over to the dottedlinfe position in Fig. 3 and swings the rock shaft 43with it. a This raises the'rod 40 and thus swings the shield 42 up linto the dotted line position-shown in Fig. 1, Itis to be noted thatthis actionis automatic and that it takes place in definite relation tothe pasted'spots 64 in their rotation. It may be statedhere that theturning of the rock shaft 43 into the lastlnamed position brings thenotch 61 into registration witlrthe bolt 60 and the spring ,62, thusforces the bolt into the notch. Now, after the web is pasted, theoperator pulls down on tlie lever 59 and swings :the rock' shaft back toits original' osition so as to cock the shield in its dotted triggerllever 59 .to horizontal position again ready for the next operation.

AThe propelling rollers for the replenshing web roll B at the topsof themachine 'have been mentioned-and the way in which they are operated willnot be described. The rock shaft'43 carries at oneend a lever 80 which`has at its.end a stud'82." This stud works in s a' slotted link 83whichispivoted by a stud 84 at its lower end to one of the' arms 38.

When the rock shaft 43 turns to the left *from its cocked position, asabove described, the stud 82-will bring up against the top of the slotinthe 'lever 83 and raise this with the arm 38. Thistur'ns the shaft 33and raises all three of thearms 38 and rubber 'rolls 39 so thatwhen theshield 42 is brought back to the dotted line position shown in F ig. 1the rolls 39 will also be raised out of contact with the surface of thereplenishingroll.

This having been accomplished, the mechanism .is allowed to perform themotion of replenishment. operator presses on the end of the rod 70. Thismovesthe rod' 68 over the finger 74 'and the next time the cam 66 comesaround, that is, the next time the pasted spots 64 come into theposition shown in Fig. 5, this will discharge the trigger mechanism andthrow the shield from the position in lfull lines in Fig. 1 to thatlshown in dotted lines, so as to let the paper web come firmly intocontact with the surface of the upper web roll B, as

Ashown in Fig. 6. It will be observed that this contact of the two webscannot occur until one of the pasted rolls is in such position that ythere shall have been' established a firm contact of the two webs beforethe 'paste of one web shall aflix it to the surface of the other.

This is regulated bythe shield which keeps the webs apart untiltheproper time. But the cam 66 determines the exact instant at which the'contact is made and as the paste can be applied to the replenishingroll at a ,point that may always bear a definite relai blade up: It isheld way down out of the way by a headed spring pin 95 slanted on oneside lso as to act automatically to hold up the arm,l

having the weight, after'it has once swung 'above it assliown in Fig. 1in dotted lines.

A rod 93 guided in a guide 94 normally moves down to engage this leverand holds the serrated blade 90 in an intermediate position but awayfrom the nearly exhausted roll when the shield 42 is down. The upper end'of this rod Iis pivoted to the arm'41 and obviously it is raised -whenthe shield moves up. Thus,

when the trigger-is released, the knife blade 90 comes up slowly intoVcontact with the expiring web roll from its intermediate position andthe expiring web will be severed from the running web at thistime'immediately afterpasting.4 To summarize, the operation is asfollows:

V Start-ing with the parts in the position shown A in dotted lines inFig. v5, the web on the roll y at -A is allowed to run nearly out. Th'enthe lever 59, with the bolt' 60 in the. hole 61, is

turned down and the shield 42, Propellers 39- yand rod 93 are thusbrought down and the trigger 52 cocked. This bolt 60 is then dis engagedfrom the hole and the lever 59 raised i tothe position shown in Fig. 3.The 4reduction of the roll'A to nea-r its exhaustion point tsoon bringsthe web W into contact with the When the time arrives they Leases@erator presses on the end of the rod and holds it in against its springduring prac- I ticallv a rotation of the roll B.1 At the proper timeduring that rotation the cam 66 releases the trigger 52. The spring48turns the rock shaft 43 to the dotted line position in Fi 3 and thearms 44, 45 and 80 turn with it. T ey raise the shield 42 and thepropelling rollers 39 and allow the weight to raise the Ysevering blade90 to the position shown in Fig. 6. Thus the pastin is done, and the oldweb severed. The ol web core is removed at A.

Now the motor 15 is started and themagazine turned a third of arevolution. The lever 91 is turned up by hand to move the severing bladedown out of the way. Itis moved far enough for the lever to snap overthe bevelled end of the spring pin 95 whichl holds the blade in itslowermost osition. When the new roll gets to the position B the old rollmandrels are in the position C ready 'to receive a new roll.'

It will be seen, therefore, that these operations are entirelyautomatic, while the machine is set by hand by turning the lever 59,

that could be done at any convenient time during the o eration of thenew roll, but is not done unt' the old web becomes nearly exhaustedbecause otherwise it would keep the new roll rotating unnecessarily. Theonly thingprequired to 'start the 'machine is to2.

touch the button constitutingthe end of the rod 70 and push itin. This,however, does not-by itself determine the exact instant of pasting butmerely determines during which rotation of the web vroll B it shalltakeiplace.

The exact instant of operation is determined l11o at full speed .Withoutany reductionat all by the cams 66; The press all the time runs andwithout the need of any further manipulation. The severing' blade, ofcourse, is released and set in position ready to operate by' pushing vinthepin 95 as stated.
